STEP 1) Remove top cover screws (4x) and high voltage cover screws (2x) provided STEP 2) Locate, mark, and drill wall mounting points (2x 6x customer supplied) The plastic enclosure itself can be used as a template for marking the drill locations on the wall. #8 Fastener If the meter is not available for use as a drill template, a drawing indicating the spacing between mounting holes can be found in the appendix. The centerline holes are intended for fastening to wall studs. If hollow wall fasteners are used, the outer 4 mounting points are recommended. 8

10 STEP 5) Attach high voltage cover IP30 TOUCH SAFE (with internal cover installed) STEP 6) Connect CT and Communications Wiring Connecting Voltage Connect the voltage leads (L1, L2, L3, and N, as necessary) to the meter through a dedicated disconnect or circuit breaker. A voltage lead of 14 AWG THHN Minimum 600VAC rating (or equivalent) is required. IMPORTANT: Verify the circuit breaker is marked as the disconnect breaker for the meter. 10

11 Wiring the AcquiSuite Ally Meter in a 3-wire, Split ɸ Service Panel High voltage MAY BE PRESENT. Risk of electric shock. Life threatening voltages may be present. Qualified personnel only. 3-Wire, 1 Phase used On MAINS L1-N, L2-N (RōCoils Shown) Connect the Neutral wire to V INPUT 1 (N) on the meter Meter is powered from L1 to L2 on the V Input 1 terminal (Label as Disconnect)) Single Phase 110 VAC Plug Loads L1-N or L2-N Single Phase 220 VAC Plug Load L1-L2 3-Wire, 1 Phase Split Load L1-N, L2-N Illustrating the intended wiring configuration for each of the Service Types available in the Service drop-down list under Meter Setup EXAMPLE LOADS: Single Phase L1-N or L2-N 110 VAC: Lighting, Appliance, Living Zone Single Phase L1 L2 220 VAC: Water Heater, Clothes Dryer, Equipment with no neutral wire. Split Phase L1 L2 220 VAC: Service Entrance, Equipment with neutral wire. 11

12 Wiring the AcquiSuite Ally Meter in a 4-wire, 3 ɸ Service Panel 3 Wire, 3 ɸ used On MAINS L1-N, L2-N, L3-N (Rogowski Coils Shown) Connect the Neutral wire or Ground wire to V INPUT 1 (N) on the meter Single Phase Branch Loads L1-N Meter Power Connect all phases to the V INPUT 1 terminal (Label as Disconnect) 4 Wire, 3 ɸ WYE load (Neutral Current) L1-N, L2-N, L3-N 3-Wire, 3 ɸ DELTA load (No possibility of Neutral Current) L1-N, L2-N(est), L3-N Illustrating the intended wiring configuration for each of the Service Types available in the Service drop-down list under Meter Setup Note: The AcquiSuite Ally Meter Series uses the Neutral Terminal as a voltage reference. For systems without a neutral conductor, Leviton suggests connecting a ground wire to this terminal. If the neutral terminal is left open, L-L measurements will be accurate, but L-N measurements may not be symmetric. If a ground wire is connected to the Neutral terminal, <2mA will flow into the ground wire. 12

13 Wiring the CTs to the AcquiSuite Ally Meter The image below is the counterpart to the service panel illustration and indicates how to connect CTs to the input terminals on the AcquiSuite Ally, for each service type. For service types that are not specifically listed, it is recommended to choose single phase service and configure each channel individually. Three phase loads are illustrated on the left and split phase loads on the right as an example only. Elements are fully interchangeable on the meter. Current and voltage inputs must be installed in phase for accurate readings (e.g. CT1 on Line 1, CT2 on Line 2) Orientation is critical: Ensure that all CTs are properly oriented with the line and load, as marked. Failure to install CTs in the correct orientation and on the correct phase will lead to inaccurate meter readings. 13

14 14 Revision C (12/18)

15 Communication Verification Revision C (12/18) Verification includes confirmation of BOTH the physical interface settings (Serial or Ethernet) and the protocol (Modbus or BACnet) settings. The LCD User interface can be used to quickly confirm the settings required for each combination of interface and protocol. The interface is intuitive and groups together commonly associated registers. The complete interface is presented in Appendix A as a navigational map. Arrows indicate how to move from one menu display to the next. A Reverse Contrast entry in the documentation indicates the active menu item in a list which corresponds to a blinking character in the physical LCD. The ENTER button is used to select a property and up / down buttons are used to select among the values supported by the meter. Note that changes to the meter configuration are limited to the communication interface using the LCD. If additional changes (such as CT type) are required they must be made using a software interface. Example LCD Navigation AcquiSuite Ally Configuration Console / Web Application If your AcquiSuite Ally model does not include the LCD user interface or if you prefer to verify the installation using software, then verification is facilitated through the AcquiSuite Ally 15

16 Configuration Console PC application or the Web App which shares a common design. Refer to the section on Configuration Details in the full user manual, or the AcquiSuite Ally Web App. Pulse Inputs Ally ACM12 meters are equipped with 4 pulse inputs and Ally ACM48 meters (hardware version I) are equipped with 2 pulse inputs. Pulse counting supports accumulation of consumption data from any external meter using a dry contact (Form A Relay) or open collector outputs. The AcquiSuite Ally pulse inputs are compatible with low speed meters. The pulse duration must exceed 50mS in both the logic low and high state allowing for a maximum input frequency of 10 Hz. Pulse scaling, resetting and accumulated values are accessed through registers and are system in scope. Refer to the register list, Obvius Ally Configuration Console, or videos for more information. >50 mec Typical Pulse Sequence >50 mec 16
